OEM BMW structural foam

Hey everybody, I'm selling a box of the oem structural foam that bmw uses to reinforce the e46 subframes. This is done via injection through the trunk. I believe bmw discontinued this foam but it sold for upwards of 180 dollars. I was going to use this in my m3 but I chose to weld in plates instead.

I'm not a qualified engineer yet, but from my opinion the foam could be a better option strength wise as it makes the whole subframe more rigid, instead of just the mounting points for the carrier. You can choose to do both but, in case of subsequent failure, additional welding could be required and I don't know how this foam would react to the extreme heat once added to your subframe.

I'm selling this kit for 130 shipped in the U.S. PayPal only please.
Local pick up also accepted. I'm in the San Diego area.
P.m. If interested. Thanks

Unfortunately I don't think this stuff has a very long shelf life. Please correct me if I'm wrong.

So long as it is unopened and unmixed, it has a very long shelf life.

Thanks mkodama. I believe he is right. These are completely sealed. Each dispenser has 2 compounds that react when mixed. I see no reason why it should "go bad". I bought this kit from the last of a BMW dealers stock just a year ago.
If they still had it for sale a few years after the date on it, I'm sure it must be ok.

To do a full repair you should weld the plates in and also use the foam afterwards man.

Yes, both would be ideal. I had an m3. With more power comes a greater risk of failure. I did develop more cracks around the plates I welded in. I wanted to have the option to reweld in the future.
I think a non boosted non m would be trouble free after performing both to it.

It has a shelf life and an experasion date on it. Looks like yours says 09. They wouldn't put a date on it if it was good until opened....when I ordered mine from thebmwpartstore.com mike (the owner) mentioned to me he was going to make sure it wasn't expired before he sold it to me because he was aware of the shelf life also.

That being said I have some that is expired 2012 and I was thinking I might use it anyway... I only got about half of one injected into the cavity now but I was holding off because i started considering future welding...

Glws, im not trying to put anyone down just hoping to educate or maybe become educated if someone knows more than I do.

The way I see it, it's more of a "best if used by" date on it.
Anyways. Price is negotiable. Come guys, throw some offers!

That's debatable. Welding in plates causes you to lose rust protection in an inaccessible part of your car. For people in high salt and/or high humidity areas, that means once you weld down those plates, you just started a countdown until it fails again from but from rust.

Part of the reason BMW picked the glue repair is likely for this reason, it's permanent and there is no loss in corrosion protection, not to mention there are no additional costs from welding.
